LOGGING-BLOCK.

Specification of Letters Patent.

Patented Dec. 29, 1914.

Application filed May 21, 1914. Serial No. 840,010.

To all whom it may concern:

Be it known that I, CHARLES E. FAXoN, a

citizen of the United States, and resident of Lindberg, in the county of Lewis and State of Washington, have invented certain new and useful Improvements in Logging- Blocks, of which the following is a specification.

This invention relates to logging and the main object thereof is to transport logs from point to point, by cable, around hills, stumps, rocks, etc., in very irregular paths, continuousl and without attention thereto other than at the starting and finishing points.

Logs have heretofore been transported by cable, and in very irregular paths, by connecting the blocks or sheaves to suitable stumps, rocks, and the like, and through which the log dragging cable is rove but, in View of the fact that the log could not very well pass through the block, or even the short cable length connecting the same with the main, endless, cable, it has been necessary to signal the donkeyman to stop his engine, then disconnect the short cable length from the main cable, on the near side of the block, and then again. connect the short cable on the far side of the block, this requiring that a man be stationed at each block and, also,

resulting in great loss of time in the stoppage of the engine for the purpose stated. It wasin order to overcome this labor and loss of time that my invention was designed, it being possible thereby to transport logs continuously and without the'labor of cable shifting at each block as described, my invention consisting of a block or sheave which permits the short log cable to pass between the cheeks thereof, without interruption.

A further object is to so construct my block as to positively prevent the main, endless, cable from escaping from the block; and a further object is to provide means for locking the cheeks of the block together, at the outer end of said block, without interference with the log cable passage through said block.

My invention is fully set forth in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in'which;-

Figure 1 is a View of my entire apparatus transporting a log from one point to another; Fig. 2' is an enlarged section of my block, taken on the line 2-2 of Fig. 3; Fig. 3 is a section taken on the line 3-3 of Fig.

- 2; Fig. l is a plan view of my block, broken away on the line 4;4e of Fig. 3; Fig. 5 is a side view thereof, broken away on the line 33 of Fig. 2, but with the parts in different positions than as shown in Fig. 3; Fig. 6 is a section taken on the line 2-2 of Fig. 3, looking up; and Fig. 7 is a view of a detail of the log transporting cable.

In the drawings forming a part of this application I have shown an endless cable a rove througha plurality of blocks 6, secured to stumps a and a and moved by means of a donkey-engine (4 the log a being connected with the cable a by means of a short cable length a.

Each of the blocks 6 comprises a central member 5 having a strap slot 6 at one end thereof, and being hollowed out to form upper and lower chambers b and b the partition b therebetween being slotted at 6 and the lower side of the member Z2 is cut away, as shown at 6 a slot 6 dividing said member into upper and lower portions at the forward end thereof, and said member is also hollowed out circularly, as shown at Z2 the periphery of which is outwardly enlarged,

as shown at b, Fig. 6, and said member 6 is provided with side plates or cheeks c and 0 each of which has a centrally arranged circular hole 0 and 0 respectively, therethrough.

Pivotally mounted at d is a forked lever (P, the upper fork (Z of which is in the upper chamber 79* whereas the lower fork (Z projects through the opening 22 and into the lower chamber 6 the outer end of the fork 6Z3 being again forked, at d to embrace the reduced portion 6 of a stub shaft 0 vertically movable in the partition b and the lower fork 614 being again forked, at (Z to pass on each side of a conical pulley e mounted on the shaft 6 in the chamber 6 a coil spring 6Z7 normally maintaining the lever d in lowermost position, and a handle (Z is provided for the shaft 6 and it will be noted that the stub shaft 6 projects, normally, below the slot 6 in the member 6 and is slidable in the cone pulley 6 thus permitting the independent revolution of the said pulley.

Revolubly mounted in the recess 6 of the member 6 is a complemental cone pulley 7, carried by a stub shaft f rotatable in the side plate 0 said cone pulleys being spaced apart a distance slightly'greater than the width of the slot 6 in line therewith and, in the normal position of the parts, thestub shaft 6 rests on the upper end of the pulley 1 Riivolubly mounted in both upper and lower portions of the member 6 above and below the slot 6", is a turnstile f, the outer ends of the arms of which are outwardly tapered to approximately fit the enlarged groove b Fig. 6, whereby the said arms hold the portions of the member 6 against separation, this being clearly shown at 7, and one of the arms of said turnstile, and sometimes two, is arranged across the slot 6, as clearly shown in Figs. 3 and 5.

Referring again to the cable a, Fig. 1, it will be seen that I provide a plurality of enlarged links a in the position of the short cable length a, the end links being tapered to the'approximate diameter of the cable a,

one of these end links being shown at a Fig. 7, and said links are. of considerably greater diameter than is the cable a, for a reason about to be described.

In the movement of they cable proper through each of the, blocks b the shaft 6 is in the position shown in Fig. 8, to prevent the cable passing out of the block through the slot b? which it would otherwise do for the reason that the width of the said slot and the space between the cone pulleys is greaterthan is the diameter of the'cable,

1 and if it is desired to remove the cable at any time all that is necessary is to raise the handle (i thus removing the said shaft from its normal position into the position shown in Fig. 5.

As shown in Fig. 1, the short cable length a is connected with the main cable at about the central portion of the link a arrangement and, when the first link a enters the block, it impinges on the under side of the arm 03 of the lever (Z2 and, because of the tapered form of this link, said lever is forced upwardly against the spring 03", thereby carrying the shaft 6 upwardly because of the arm d of said lever, and the space between the cone pulleys is cleared for the passage of the short cable length a which is connected with the log, said cable length passing through the slot 6 in its passage through the block, and the log is therefore carried past'saidblock without the necessity for disengaging the cable length a from the main cable, and the shaft 6 is held in such raised position until the end link a permits the lever (Z to gradually resume its normal position and thus permit the shaft 6 to again close the space between the cone pulleys, for main cable confinement, and this passage of the cable length a occurs at each of the blocks, and it will therefore-be seen that a log may be dragged over a very tortuous path to avoid 'hills,

rocks, trees, stumps, etc., by'merely arranging my blocks accordingly, and the present necessity for constant attention, and engine stoppage, at each block is avoided.

The turnstile f while freely revoluble, locks the top and bottom portions of the block together because ofthe enlarged arm ends and enlarged periphery of the recess 12 but when a short cable a is passed through the slot 6", itstrikes against the arm arrangedacross the said slot and revolves the turnstile, and its passage is'not, therefore, impeded.

My invention is Very simple in construction, installation, and use but, as will be seen from the foregoing, is a very economical factor in logglng operations, and I reserve the right to make all desired changes in the details shown and described. which come within the scope of the following claims, and, with such reservation,

What I claim as new, and desire to secure by Letters Patent, is 1. The combination with a main cabl having a short cable connected therewith for moving articles; of a block for guiding said main cable and comprising cheekplates,"

cheek plates spaced apart at their outer.

two oppositely disposed cone pulley 1 ends, members. having a space therebetween greater than the diameter. of said short cable, said main cable being of greater diameter than said space at the point of short cable connection. 7 i

3. The combination with a' main' cable having a short cable connected therewith for moving articles; of a blockcomprising cheek plates spaced apart at their. outer ends, two oppositely disposed cone pulleys ai having a space therebetween greater than the diameter of said short cable, means for spanning said space to prevent escape of said main cable, and means connected with ios iio

said main cable for moving said preventive means from between said the passage of said short block.

4:.The combination with a main cable pulleys to permit cable across said having a short cable connected therewith for I moving articles; of a block comprising cheek plates spaced apart at their outer ends, two oppositely disposed, spaced, cone pulley members, means for spanning said space between pulley members, to confine 55 said main cable, means for moving said spanning means to permit the passage of as my invention I have signed my name in iaid lshot cable across iaidlblock, and Imeans presence of the subscribing Witnesses.
